Heating to high temperatures in air or oxygen.
- The term is most likely to be applied to a step in the preparation of a catalyst.
- In sol-gel processing the term applies to the heating of a polymer network
containing metal compounds to convert it into an oxide network.
- Modified from previous definition. The definition proposed here is more
explicit about the elevated temperatures that are required.
